Why does a gas furnace trip its breaker?

You may have discovered that your gas furnace stopped laboring, only to find out that the breaker to your plan was tripped! This occurs every once in a while, plus it can be challenging to figure out what caused the problem, but regardless of which type of fuel your plan uses, your gas furnace still needs electricity to function.

There are gas furnace parts that run on electricity.

The most vital of those components is your gas furnace blower. This is the component of your gas furnace responsible for distributing warm air throughout your home, plus it needs electricity to operate, most gas gas furnaces also turn on with an electronic ignition rather than the pilot lights utilized in older gas furnaces. The electronic ignition also needs an electrical power supply to operate. Since it uses electricity to carry out its functions effectively, it will most likely trip the breaker at some point. The most likely reason that your gas furnace trips a circuit breaker is when the blower is overlaboring, then every time something restricts airflow to your system, your blower works harder in an attempt to compensate. The most likely culprit for airflow obstructions is a dirty or obstructed air filter, however when your blower works harder to push air through a dirty or obstructed filter, it will increase the blower’s energy consumption, which may trip the circuit breaker! Other concerns that may also contribute to an overlaboring gas furnace blower include duct leaks, new home air leaks, plus obstructed or closed-off air registers. On some occasions, a tripped breaker may not necessarily be your gas furnace’s fault, your gas furnace may be sharing a breaker with other appliances that caused the trip, or perhaps the circuit breaker malfunctioned.
